1. Warranty VIGO System S.A. hereby represents and warrants all Products manufactured by VIGO and sold hereunder to be free from defects in workmanship or material during a period of twelve (12) months from the date of delivery save for products for which a special warranty is given.
2. VPXC-xxS technical information 2.1. VPXC-xxS module description The VPXC-xxS is an transimpedance amplifier especially suited to work in cooperation with VIGO uncooled detectors. Both AC and DC coupling is available. Detector bias circuit is included. 2.2. Module physical dimensions Dimensions are given in millimeters. 129/133 Poznanska St., 05-850 Ozarow Mazowiecki, Poland; tel. +48 22 733 54 20; fax +48 22 733 54 26; e-mail: info@vigo.com.
2.3. Preamplifier supply voltage Preamplifier version Power supply value VPXC-0.1S, VPXC-0.3S, VPXC-1S ±15V/±50mA (±10%) VPXC-5S, VPXC-10S, VPXC-20S ±9V/±50mA (±10%) Every type of the VPXC-xxS preamplifier is internally protected against reversing the supply polarity and abnormal voltage increase. Although Preamplifier contains voltage regulators, while powering with the custom made power supply, provide the properly stabilized and filtered voltage. 2.4.
3. Getting started (regards the preamplifier itself as well as the complete IR detecting kit) 3.1. Unpacking Before unpacking, verify if there are no visible damages of the package. Report them to the manufacturer or the distributor. 3.2. Installation & connections • Mount the IR preamplifier in the measurement setup, • Connect all elements with cables provided in the package, • Make sure that all the elements are properly connected.
3.3. Switching on procedure • Do not switch on the preamplifier power supply until ALL elements of the IR detection kit are properly connected with the proper cables. • Before starting the measurements make sure the load resistance is valid. The VPXC-xxS output should be terminated by 50Ω or 1MΩ resistance depending on the bandwidth and is given in the test data provided on the module.
4. VPXC-xxS other related information 4.1. CE statement of conformity VIGO System declares that IR detection kit is fully compliant with: EU Low Voltage Directives: 73/23/EEC, 93/68/EEC EU Electromagnetic Compatibility Directives: 89/336/EEC, 91/263/EEC, 92/31/EEC, 93/68/EEC 4.2. Electromagnetic interference To avoid the electromagnetic interferences (EMI): Please do not put any electromagnetic source close to the IR module.
5. Safety instructions To ensure safe and failure-free operation of the IR detection kit comply with the following precautions: The IR detector is dedicated to measure IR flux. Never use the detector in other applications. Never dismount the case of the preamplifier. Do not open or remove the housing of the device. It may lead to its permanent damage or/and to a risk of electric shock. Handle with care, avoid excessive mechanical shock or vibration.
6. Troubleshooting At first, please carefully read the previous parts of this manual, especially Safety instructions. If a problem persists, please check the information given below.
6.1.3. No or too weak response to optical radiation Follow through General Test Procedure. • Check your radiation source, • If you do not have any other detector to test your radiation source, move a hot object (ex. soldering iron) rapidly in front of the detector, across its whole field of view. (The higher the temperature of the object or shorter the distance to the detector, the higher the optical signal at the detector output.), • Test your detector with another available radiation source.
6.1.7. Long signal rise/fall time Check through General Test Procedure. Check: • The shape of the pulse with another detector if possible, • The operating conditions (bias, optical setup), • If impedance of the detector, cables, preamplifier and your read-out instrument are matched. 129/133 Poznanska St., 05-850 Ozarow Mazowiecki, Poland; tel. +48 22 733 54 20; fax +48 22 733 54 26; e-mail: info@vigo.com.
